<P>PROBLEM TO BE SOLVED: To inform a user of the number of unoccupied taxis at proper timing. <P>SOLUTION: Current position data of a user is obtained (step S50). An arrival prediction time at which the user arrives at an arrival station is calculated on the basis of an arrival station database storing the arrival station of the user in association with a user ID and the current position data (step S52). When a current time is at a predetermined time before the arrival prediction time, the number of unoccupied taxis in the vicinity of the arrival station is obtained, and on the basis of a reservation condition list, whether the number of unoccupied taxis is greater than the number of taxis in reservation condition is determined, and if the number of unoccupied taxis is smaller, the number of unoccupied taxis is informed to the user (step S58). <P>COPYRIGHT: (C)2013,JPO&INPIT |
